Hello there,

this is my first contact with dvb-t and so far it actually worked quite
well: the blue led is already on :) but now im stuck

what i did so far:
i compiled the necessary modules from the 2.6.13 kernel, copied the
necessary firmware (dvb-usb-avertv-a800-02.fw) to /lib/firmware and
modprobed the modules. as a result dmesg reported a success and in
/dev/dvb/adapter0/ the devices demux0, dvr0 and net0 were created.
happily i installed the dvb-applications and tried to scan for channels:

main:2216: FATAL: failed to open '/dev/dvb/adapter0/frontend0': 2 No
such file or directory

Well so I checked out the latest cvs but still no change. Well there was
some error now when loading the firmware but after replugging the device
it worked again. But still no frontend0.

I have those modules loaded as described in the linuxtv dvb-usb wiki page:
 - i2c-core
 - crc32
 - firmware_class
 - dib3000-common
 - dib3000mc
 - dvb-usb
 - dvb-usb-dibusb-common
 - dvb-usb-a800
 - dvb-core.ko
 - dvb-pll.ko

Well actually in the second attempt I used the ./insmod.sh load command
which loaded about everything possible (but crc32 which i have compiled
into the kernel).

Well do you have any hints?
Here's the dmesg output for the second attempt (dvb-kernel cvs-version)
